------- Additional Comments from Kenneth Russell <kbr at google.com>
>From the ChangeLog:

Added offscreen code path for WebGraphicsContext3DDefaultImpl which works with
the compositor integration in both DumpRenderTree and test_shell, since both
pass a non-null WebCanvas* to WebViewImpl::paint and thereby trigger the
compositor's readback code path. Added support for
--enable-accelerated-compositing to DumpRenderTree.

Tested in both test_shell and DumpRenderTree on Linux, the latter by modifying
a compositing layout test, dumping the pixels and verifying that they matched
the output when the compositor was active.
